This means i have to connect the R earphone wire to my right ear & the L earphone wire to my left ear. What will happen if i interchange the R designated wire to my Left ear & L designated wire to my Right ear?. i.e. interchange.

Did you find any difference after you interchange the wires listening the same song twice? I did not find any difference. Thanks & Regards, Prashant S Akerkar Title: Re: Earphone - Left & Right Ear connections. Post by: duddy on Mar 22, 2020 No difference at all, changing the polarity won't change the sound.

So why there are two letters L & R respectively in the earphone wires? Assumptions ------------- L stands for Left ear connections R stands for Right ear connections. Thanks & Regards, Prashant S Akerkar Title: Re: Earphone - Left & Right Ear connections. Post by: biolove on Mar 22, 2020 They're labelled L and R because of their oreintation. The left earbud is built to fit into the left ear, the right is built to fit the right ear, that's all.

But after interchanging wires in the two ears, we could not find any difference in terms of sound /audio hearing from the same song? Thanks & Regards, Prashant S Akerkar Title: Re: Earphone - Left & Right Ear connections. Post by: bio_man on Mar 22, 2020 I think biolove is referring to the way earbuds are made only to fit one side of the ear correctly. In addition, some songs will increase the intensity of sound at one ear depending on the beat that's produced. That's another reason why they're labelled the way they are too
Title: Re: Earphone - Left & Right Ear connections. Post by: prashantakerkar on Mar 23, 2020 Thank you. It could or maybe be in case of wireless earbuds because when i check with my wired earphones both the earbuds wires are fitted properly in both the ears even after interchanging.

Post by: bio_man on Mar 23, 2020 Thank you. It could or maybe be in case of earbuds because when i check with my earphones both the earbuds are fitted properly in both the ears even after interchanging. i.e. They are getting fitted properly in both the ears even after interchanging. Thanks & Regards, Prashant S Akerkar That's strange b/c usually they're specific for your specific ear shape. Anyway, many songs take advantage of "panning" , this is when music goes from one ear to another. Changing the polarity might mess up with that. Only way to test is to hear music that uses the "panning" technique, and see if it changes the effect. Title: Re: Earphone - Left & Right Ear connections.

Its a lovely song & music from Bee Gees Brothers. https://m.youtube.com/watch?v=pMvHuxjFoNo&list=RDpMvHuxjFoNo&start_radio=1 What's your opinion? Thanks & Regards, Prashant S Akerkar Title: Re: Earphone - Left & Right Ear connections. Post by: bio_man on Mar 23, 2020 Great song...
Good example of panning: https://www.youtube.com/watch?v=Uj_-od8gJUA Try testing how this sounds with opposite polarities Also, try this: https://youtu.be/47dtFZ8CFo8 |
